Usage

The condition component is applied when specifying component: 'condition' in your field. It needs a trigger that will toggle your condition. This can be any component usable with TinaCMS. The value is then passed to the fields method. Based on this value you can control which fields to return. If you don't return anything nothing will be displayed.

Examples

{
  name: 'frontmatter.useReadme',
  component: 'condition',
  label: 'Use Readme',
  trigger: {
    component: 'toggle'
  },
  fields: useReadme => {
    if (!useReadme) {
      return [
        {
          name: 'frontmatter.test',
          component: 'text',
          label: 'Some test',
          description: 'To prove it works with multiple fields'
        },
        {
          label: 'Body',
          component: 'markdown',
          name: 'rawMarkdownBody'
        }
      ]
    }
  }
}

{
  label: 'Internal',
  name: 'internal',
  description: 'Set to false if you want link to another website',
  component: "condition",
  trigger: {
    component: "toggle"
  },
  fields: (internal) => {
